Multi-hinge tonneau cover

ABSTRACT

A tonneau cover comprising: (a) a plurality of panels; (b) one or more hinges located between and connecting each panel of the plurality of panels; and (c) one or more rotary locks located on a first side, a second side, or both sides of one or more of the one or more hinges, one of the plurality of panels, or both, the one or more rotary locks including: (i) one or more panel caps; and (ii) one or more rail locks that create a lock with the one or more panel caps when the tonneau cover is in a closed position so that the tonneau cover is prevented from being opened proximate to the one or more hinges.

FIELD

The present teachings relate to a tonneau system including one or more expansion links that assist one panel in rotating relative to another panel; one or more covers that extend over all or a portion of a cover and a hinge and/or assists in holding a hinge together, preventing fluid from penetrating through or around hinge joints, or both; one or more expansion caps that extend a hinge to a location proximate to or over a rail cap and/or a support rail; a standing hinge that lifts one or more panels as one panel is rotated relative to a second panel; one or more connectors that connect a tonneau to a vehicle and/or prevent longitudinal movement of a tonneau cover relative to a vehicle; one or more rotary locks that prevent a hinge from being vertically moved relative to a vehicle and/or vehicle bed when the tonneau cover is in the closed position; or a combination thereof.

BACKGROUND

Tonneau covers are typically added to beds of vehicles to close the bed of the vehicle. Some tonneau covers may be locked to prevent theft. Some tonneau covers may prevent the ingress of fluids and debris into the bed of the vehicle so that the contents of the bed may be maintained in a clean and dry state. Tonneau covers may be used with virtually any vehicle with a bed such as a truck, El Camino, UTV, SUV, any vehicle with a bed, or a combination thereof. Some tonneau covers may be found in U.S. Pat. Nos. D830,282; D830,283; 5,427,428; 9,333,842; 9,555,735; and 9,840,135 and U.S. Patent Application Publication No. 2018/0118004 all of which are expressly incorporated by reference herein for all purposes.

It would be attractive to have one or more expansion links that connect two or more panels together and each expansion link provides a specific amount of rotation of a first panel relative to a second panel. What is needed is a single cover that extends over all or a portion of a panel and a hinge so that the single cover prevents fluid from penetrating though the hinge; the cover holds the hinge together; the cover disconnects from the hinge, the panel, or both to facilitate movement of the hinge without restriction by the cover; or a combination thereof. It would be attractive to have a tonneau cover with hinges that include one or more expansion caps that extend a hinge to a location proximate to or over a rail cap, a support rail, or both. What is needed is a tonneau cover that includes one or more standing hinges that lift one or more panels from a rail cap, a header panel, or both so that the one or more panels are spaced a distance away from the rail cap, the header panel, or both when one of the tonneau covers is rotated relative to a second tonneau cover. It would be attractive to have one or more connectors that connects the tonneau cover to a vehicle and the one or more connectors are movably locked within a track so that the one or more transverse connectors are movable in a transverse direction while the one or more connectors prevent longitudinally movement of the tonneau cover. What is needed is a tonneau cover including one or more hinges that include one or more rotary locks that prevent the hinges from being lifted vertically when the tonneau cover is a closed position.

Accordingly, the specific embodiments of the present teachings as set forth are not intended as being exhaustive or limiting of the teachings. The scope of the teachings should, therefore, be determined not with reference to the above description, but should instead be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. The disclosures of all articles and references, including patent applications and publications, are incorporated by reference for all purposes. Other combinations are also possible as will be gleaned from the following claims, which are also hereby incorporated by reference into this written description.

The vehicle as discussed herein may be any vehicle that has an open area, which may be covered. The open area, preferably, is a bed. The vehicle may be a truck, a trailer, El Camino, a UTV, ranchero, Gladiator, or a combination thereof. Preferably, the vehicle is a truck or a pickup truck. The vehicle may have one bed. The bed may function to store and carry articles. The bed may carry virtually any article that may fit within the bed. The bed of the vehicle may be an open area for storing items. The bed may be 1 m or longer, 1.5 m or longer, or 2 m or longer. The bed may be 3 m or less or 2.5 m or less. The bed may be connected to one or more tonneau covers via one or more connectors.

The one or more connectors may prevent longitudinal movement of the tonneau cover relative to the vehicle. The connector may tether the tonneau cover to a bed of a vehicle, a fastener, or both. The connector may connect to one or more fasteners. The connector may be adjustable. The connector may connect to a fastener or a fastener may connect one or more parts of the tonneau cover together. The connector may be part of a tonneau connector or include a tonneau connector. The connector and the fastener may be directly connected together. Preferably, the connector and the fastener may be indirectly connected together.

The one or more fasteners may function to connect two or more parts of a tonneau cover together. The fastener may be part of the vehicle. A tether, connector, tonneau connector, the tonneau cover, or a combination thereof may connect to a connector of the vehicle to restrict movement of the tonneau cover. The one or more fasteners may connect a header panel, a header guide, a header cap, a spacer cap, an expansion cap, or a combination thereof to a panel, a hinge, or both. The one or more fasteners may fit within a track. The one or more fasteners may act as a stop. The one or more fasteners may restrict movement within a track. The one or more fasteners may be threaded. The one or more fasteners may be a screw, nut, bolt, pin, locking member, “T” shaped, “L” shaped, have a head that fits within the track, have a head that is located outside of a track, or a combination thereof. Preferably, the one or more fasteners, tonneau connectors, or both may assist in connecting a header panel to a side rail, a rail cap, a support rail, or a combination thereof. The one or more fasteners may prevent or restrict movement of the rail cap, the support rail, or both relative to a header panel (e.g., restrict movement to 1 cm or less or 0.5 cm or less).

The rail cap may function to connect to a top of the vehicle, a top of a bed, or both and create a support structure the tonneau cover, one or more panels, or both. The rail cap may extend above an original rail cap. The rail cap may replace an original rail cap. For example, an original rail cap may be removed and an aftermarket rail cap attached in its place. The rail cap may create a recess so that the tonneau cover when in a closed position a top of the tonneau cover is flush or sub flush with a top of the rail cap, a top of a side of a bed, or both. The rail cap may attach to a wall of a bed and assist in connecting the panels to the bed, assist in removing fluid, or both. The one or more rail caps may be connected to the vehicle via clamps, holes in stake pockets, holes in the sidewalls, or a combination thereof. The rail caps may be flush mounted. Each side of the vehicle may include a rail cap. The tailgate of the vehicle may include a rail cap. The rail caps may taper from a front end towards a rear end. The rail caps may direct fluid through the stake pockets, an end of the vehicle, out of recesses, through the tailgate, or a combination thereof. The teachings of the rail cap as found herein including the teachings found in application Ser. Nos. 62/640,799 and 16/296,578 are expressly incorporated by reference herein for all purposes including those of connection, fluid management, flushness, sub-flushness, or a combination thereof. The one or more rail caps may be part of a support rail or used with a support rail. A support rail may connect the tonneau cover to a vehicle bed, a vehicle, a side wall of a bed, or a combination thereof instead of a rail cap.

The one or more support rails may function to support one or more sides and/or edges of a tonneau cover. The one or more support rails may extend over an original rail cap. The one or more support rails may be connected to the vehicle, the bed, or both via one or more fasteners, clamps, or both. The one or more support rails may connect to and extend along a side of a bed. All or a portion of the one or more support rails may extend into a vehicle bed. The one or more support rails may have a portion that extends over a top of a side wall of a bed. The one or more support rails may be located below a top plane of the bed so that the tonneau cover may be flush or sub-flush when the tonneau over is in a closed position. The one or more support rails may include one or more channels that remove fluid, prevent fluid from entering a vehicle bed, or both. The one or more support rails may include one or more seals that form a seal with the tonneau cover to prevent fluid and debris from entering the bed. The one or more support rails may extend an entire length of a bed of a vehicle. The one or more support rails may contact a first side, a second side, or both sides of one or more panels of a tonneau cover and preferably both sides of a tonneau cover.

The one or more tonneau covers may function to enclose all or a portion of a bed. The one or more tonneau covers may lock items within a bed. The one or more tonneau covers may prevent fluid, debris, or both from entering into the bed. The one or more tonneau covers may include one or more panels. The tonneau cover when in a closed position may prevent fluid, debris, or both from entering a bed and may protect the contents of the bed. The tonneau cover when in a stored position may allow for ingress and egress into and out of the bed, the contents to be accessed, or both. The tonneau cover fold and be stored substantially vertically behind a rear window of a cab. The tonneau cover may be a plurality of panels that are connected together via one or more hinges. The plurality of panels may each be movable between a stored position and a closed position.

The tonneau cover in a closed position may function to cover all or a portion of a bed and preferably a bed of a vehicle so that the contents of the bed may be protected, covered, or both. The closed position may be where one or more panels of the tonneau cover extend in a plane, in a plane parallel to a bottom of a bed, cover a portion of a bed, or a combination thereof. When all of the panels are in the closed position the bed may be entirely covered, locked, substantially fluid resistant, or a combination thereof. When the panels are in the closed position the panels may be coplanar. Some panels may be in a closed position and some panels may be in a stored position. For example, a tail panel may extend over a central panel so that a very end of a bed may be exposed while the rest of the bed remains covered.

The stored position may function to expose all or a portion of a bed so that contents of the bed may be accessible. The stored position may be where one or more panels are moved relative to one or more other panels into a nested configuration, a stacked configuration, or both. The stored position may be where one panel is rotated over another panel. The stored position (e.g., fully stored position) may be where two or more, three or more, or four or more panels are stacked one over another and then turned on end so that substantially all of the bed is exposed. The stored position may be where a stack of panels extends generally parallel to the rear of a vehicle (e.g., ±15 degrees or less, ±10 degrees or less, about ±5 degrees or less, or about ±1 degree or more). For example, the panels in a fully stored position may be angled towards a rear of a vehicle or a rear of a vehicle cab. The fully stored panels may rotate beyond 90 degrees and may rest upon the one or more bumpers and the one or more bumpers may prevent further rotation of the panels. The fully stored panels may be where a tail panel and three central panels are in a generally parallel position and then turned on end to extend generally vertically above a header panel.

The panels may function to movably connect together to enclose a bed and to move so that the bed is accessible to a user. The tonneau cover may include two or more panels, three or more panels, four or more panels, or even five or more panels. The tonneau cover may include a header panel, a tail panel, and one or more panels therebetween. The tonneau cover may include one or more panels, two or more panels, three or more panels, or four or more panels between the header panel and the tail panel. The panels between the header panel and the tail panel may be central panels. The central panels may include a first central panel, a second central panel, a third central panel, or a combination thereof. The header panel may be a panel that connects the tonneau cover to the vehicle. The header panel may not be located at an end of the tonneau cover. The panels in a closed position may all be located within a single plane. The panels may be connected together and rotatable relative to each other. The panels may be rotated so that one panel is located above another panel in a stacked configuration. The panels may each include a core, an upper cover, a lower cover, or a combination thereof. The panels may be connected to the hinges by a fame, a cover, one or more links, or a combination thereof. The panels may have an upper cover that extends along an all or a portion of the panel and then over all or a portion of a hinge. The panels may have a lower cover that extends along all or a portion of rear surface of a panel and stops before covering the hinge. The lower cover may cover a portion of a hinge.

The one or more covers may function to hold a hinge together, seal a hinge, prevent fluid from entering a hinge, support a first panel above a second panel, or a combination thereof. The one or more covers may extend from a first panel across all of the panels and hinges and terminate at an end of a last panel. The one or more covers may extend across one panel and one hinge. The cover may extend across one or more of the hinge joints or all of the hinge joints. The cover may have a connection location on each of the hinges. Preferably, the cover may have a connection location on each of the hinge joints of a hinge. The cover may connect to each of a plurality of hinge joints of a hinge and the cover may permit movement between each of the hinge joints, but the cover may maintain all of the hinge joints connected together so that the hinge joints create a movable hinge. The cover may connect the panels to a hinge so that the hinge is movable relative to the panels. A rotary stand may be connected to the panels or held in place relative to the panels by a cover. The cover may have a connection location on each of the spacer bars. Preferably, an upper surface of a hinge joint, a spacer bar, a rotary stand or a combination thereof have a connection location with a cover. The one or more covers may be made of a flexible material. The one or more covers may be made of an abrasion resistant material. The one or more covers may be folded or bent without failing. The one or more covers may be folded or bent 1,000 times or more, 10,000 times or more, 50,000 times or more, 100,000 times or more, 250,000 times or more, 500,000 times or more, or even 1,000,000 times or more without failing. For example, the cover may be folded to angle of about 180 degrees so that a first part extends over a second part without the folded region (e.g., a region connecting the first part to the second part) breaking, failing, tearing, separating a first portion from a second portion, or a combination thereof. The cover may be folded without the connection locations disconnecting from a hinge, a panel, a hinge joint, spacer bar, rotary stand, or a combination thereof.

The one or more covers may be made of or include a synthetic material, natural material, rubber, an elastomer, thermoplastic, a polyolefin, a vulcanized material, vinyl, or a combination thereof. Preferably, the cover is made of or includes a thermoplastic vulcanizate (TPV) or a thermoplastic polyolefin (TPO). The cover may include or be connected by a thermoplastic adhesive, a thermoplastic adhesive polymer resin, or both. The cover adhesive may be made of or include a CoPolyamide, CoPolyester, Polyolefin, Ternary, Polypropylene, Polyruethane, or a combination thereof. The adhesive may be activated by heat, radio frequency (e.g., RF or HF), ultrasound, moisture, pressure, or a combination thereof. One example of an adhesive that may be used is created by Spunfab®, the teachings of which are expressly incorporated by reference herein for all purposes. The one or more covers may have a thickness of about 5 mm or less, about 3 mm or less, about 1 mm or less, about 0.5 mm or less, or about 0.1 or less. The one or more covers may have a thickness of about 0.025 mm or more (e.g., 1 thousandth), about 0.05 or more, or about 0.07 or more. The cover may be a continuously applied to the panels and self-adhere to the panels during the application process. The cover may be connected by a separate adhesive that is applied to the cover and the panels, the hinges, or both. The cover may be a film that overlays all or a portion of the tonneau cover and is connected to all or a portion of the tonneau cover. Preferably, the cover forms one continuation surface that covers an entire area of a tonneau cover (e.g., all of the hinges and all of the panels). More preferably, the cover extends over all of the joints, slats, folding regions, moving regions, hinge joints, or a combination thereof so that one continuous surface is created. The cover may be connected to all or portions of the tonneau cover (e.g., panel or hinges) and disconnected from portions of the tonneau cover (e.g., panels or hinges).

The connection locations may function to connect the cover to all or a portion of a panel, all or a portion of a hinge, or both. The connection locations may be at any location along a panel, a hinge, or both. The connection locations may connect the cover to about 50 percent or more, about 60 percent or more, about 70 percent or more, about 80 percent or more, about 90 percent or more, about 95 percent or more, or about 97 percent or more of a panel, a hinge, or both. The connection locations may connect the cover to about 99 percent or less, about 98 percent or less, about 95 percent or less, or about 93 percent or less of a panel, a hinge, or both. The panel and cover may entirely be connected by connection locations and may be free of any disconnection locations. The cover may include connection locations at every location along a panel and may be free of connection locations at a transition from the panels to hinges. The connection locations may be mechanical attachment or chemical attachment of a cover to a hinge, a panel, or both. The connection locations may be formed by a screw, a bolt, staple, a flange, or a combination thereof that extend over or through a cover to connect the cover to a panel, a hinge, or both. Preferably, the connection locations are formed by a liquid or solid adhesive. The connection locations may be formed by applying an adhesive between the panel, the hinge, or both and the cover. The adhesive may be a liquid adhesive that dries, cures, or both. The adhesive may be cured with heat, radio frequency (e.g., RF or HF), ultrasound, moisture, pressure, or a combination thereof that connects the cover to the panel, the hinges, or both. The adhesive may create a connection location that is rigid. The adhesive may create a connection location that has some elastomeric characteristics. For example, the cover may move relative to the panel, the hinge, or both by stretching the adhesive if a force is applied to the cover. The connection locations may hold the cover to the panel, the hinge or both so that the cover is immovable relative to the panel, the hinges, or both. The connection locations may maintain the cover generally parallel to the panels, the hinges, or both when the tonneau cover is in a closed position. The connection locations may maintain contact with the panels, the hinges, or both when the tonneau cover is moved and the disconnection locations of the cover may move relative to the panel, the hinges, or both when the tonneau cover is moved between a stored position and a closed position.

The one or more disconnection locations may function to be free of a connection or a permanent connection with the panel, the hinge, or both at a location proximate to or under the cover. The disconnection locations may temporarily connect to the hinge, the panel, or both but may disconnect when the panels are moved from a closed position to a stored position. For example, the disconnection locations may be temporarily connected via surface tension, tackiness, magnets, or a combination thereof, but the temporary connection may be overcome so that the cover is disconnected from the panels, hinges, or both. The disconnection locations may be regions (e.g., disconnection regions) on the panels, the hinges, or both and may function to assist in guiding fluid from a hinge joint. The disconnection locations may both assist in movement of the hinge joints and removal of fluids. The one or more disconnection locations be free of a mechanical connection, a chemical connection, or both. Preferably, the one or more disconnection locations may be free of adhesive. The disconnection locations may permit the cover to move relative to hinges, panels, or both in the stored position, the closed position, or both. The disconnection locations may permit movement of the cover relative to the hinges, the panels, or both when the tonneau cover is being moved toward a stored position or from a stored position. The one or more disconnection locations may extend over a hinge, over a panel, or both but the cover may move relative to the hinge, the panel, or both at a location proximate to the respective hinge, panel, or both. The disconnection locations may be where the cover may move, fold, or both relative to a hinge, a panel, or both. For example, when a first panel is folded relative to a second panel, a length of the hinge may be reduced due to some of the hinge (e.g., hinge joint) extending behind another part of the hinge and the cover may bend, fold, arc, bunch or a combination thereof to permit a portion of a hinge to extend behind another portion of a hinge. The disconnection locations may release from a portion of the hinge to accommodate for an increase or decrease in length of a hinge when the hinge moves between a stored position and a closed position. For example, when an extended hinge moves from a closed position to a stored position a length of hinge exposed may decrease so that the cover disconnects from the decrease in length to prevent a force from being applied on the cover. The disconnection location may be located between the spacer bars, above a hinge step, above a top surface of an expansion projection, or a combination thereof. The disconnection location may be at a hinge connector. The disconnection locations may be at a joint that is movable (e.g., between a panel and a hinge, between hinge joints, or both). The disconnection location may be a region between a top surface of a spacer bar and a location of a panel located above a frame of a hinge. The cover may extend over a space where there is a gap located between the hinge and cover. A disconnection location may extend an entire width of a tonneau cover (e.g., a width of a vehicle). The disconnection location may extend in a straight line (e.g., a first edge of a tonneau cover to a second edge of a tonneau cover). The disconnection location may be pulled flat when the tonneau cover is moved from a stored position to a closed position so that the cover appears seamless. The disconnection location may bunch when the tonneau cover is moved from a closed position to a stored position. The disconnection locations may be located at or between any of the panels. The disconnection locations may be located between the header panel and a central panel, two central panels, a central panel and a tail panel, or a combination thereof.

The header panel may function to connect the tonneau cover to a vehicle. The header panel may function to support the other panels when the panels are moved into a stored position. The header panel may connect to a rail cap, a support rail, or both and be free of rotation, longitudinal movement, lateral movement, or both. The header panel may form a base that the other panels are rotated unto so that the panels are stored along a forward region of a vehicle bed, behind a cab of a vehicle, or both. The header panel may span a width of a bed. The header panel may connect to the vehicle with header guides, connectors, tonneau connectors, or a combination thereof. The header panel may extend to a forward most end of a vehicle bed proximate to a cab of the vehicle. The header panel may include one or more header caps.

The one or more header panels may extend a header panel over a rail cap, a support rail, or both. The one or more header panels may cap an extruded portion of a header panel. The one or more header panels may be extruded, made of plastic, metal, or a combination thereof. The header panels may be sufficiently strong to support the weight of the other panels when the panels are moved into a stored position. The header cap may be made of metal, plastic, or both. The header panel may have one or more header caps at each end of the header panel.

The header cap may cover the ends of the header panel. One or more header caps may be located at each end of the header panel. The header caps may extend over or connect to a rail cap, a header panel, or both. The header caps may enclose all or a portion of a recess or a header recess within the header panel. The header cap may lock a connector within the header recess, a track, or both.

The header recess may function to create a void in the header panel, create a connection location for a header recess to connect to a hinge or an adjacent panel. The header recess may receive a portion of a hinge. The header recess may allow a panel, a central panel, a hinge, or a combination thereof to move relative to the header panel. The header recess may extend a width of the header panel. The header recess may be enclosed within the header panel when the header caps are connected to the header panel. The header recess may form a track in the header panel that a connector is located within. The header recess may allow for lateral movement of a connector. The header recess and the header guide recess may assist in connecting the header panel to the vehicle bed so that the tonneau cover is maintained in a fixed position once connected to the vehicle.

The header guide recess may function to receive a fastener, a header guide, a header guide connector to create a connection between the rail cap, the support rail, a vehicle bed, a side wall of a vehicle bed, or a combination thereof. The header guide recess allows the header guide to laterally move into an engagement with a rail cap, a support rail, or both. The header guide recess may extend an entire width of the header panel. The header guide recess may be one or more segments, two or more segments, three or more segments, or four or more segments. The header guide recess may be located within side regions of the header panel and not extend in a middle or central portion of the header panel. The header guide recess may have a “T” shape so that a fastener (e.g., a header guide connector) may not be removed once the fastener is extended into the header guide recess, but the fastener may be movable along the header guide recess. The header guide recess may directly receive a portion of the header guide. The header guide recess may be a track that the header guide, the header guide connector, or both may move along to connect the header panel to the bed. The header guide recess may receive a fastener or a connection device that connects the header guide to the header guide recess.

The header guide may function to prevent the header panel from being vertically lifted. The header guide may extend under a portion of a rail cap, a support rail, or both to prevent the header panel from being lifted, opened, moved, or a combination thereof. The header guide may slide under the rail cap, the support rail, or both to create a connection. The header guide may be made or metal, plastic, a polymer, or a combination thereof. The header guide may be sufficiently rigid to prevent movement of the header panel relative to the truck bed. The header guide may include one or more header guide connectors.

The one or more header guide connectors may connect a header guide to a tonneau cover, a header panel, a header guide recess, or a combination thereof. The one or more header guides may be a monolithic part of the header guide, may be a unitary part, may be added to the header guide, or a combination thereof. The one or more header guides may have a complementary fit to the header guide recess. The one or more header guide connectors may extend within the header guide recess so that the header guide is suspended from the header panel. The header guide connectors may be a fastener. Preferably, the header guide connectors and the header guide are a same device (e.g., one monolithic piece). The header guide connector may extend from the header guide and the header guide may hang below the header guide connector. The header guide connectors may be restricted from movement by a fastener that is located within the header guide recess. The header guide connectors may extend along the header guide recess until the header guide connectors contact a fastener that restricts movement of the header guide connector. The header guide connector may be moved into a locked position and then locked in place by a fastener restricting movement of the header guide connector within the header guide recess. The one or more header guide connectors may include one or more ears.

The one or more ears function to retain the header guide connector within the header recess. The one or more ears may be one circular ear that prevents removal of the header guide connector. The one or more ears may extend from opposing sides of the header guide connector. The one or more ears may extend from four quarters of the header guide connector. The one or more ears may be spaced apart by about 30 degrees or more, about 45 degrees or more, or about 60 degrees or more. The one or more ears may be spaced apart by about 180 degrees or less, about 150 degrees or less, about 125 degrees or less, or about 90 degrees or less. The one or more ears may have a length that is about 5 degrees or more, about 10 degrees or more, about 20 degrees or more relative to a circumference or perimeter of the header guide connector. The one or more ears may have a length that is about 90 degrees or less, about 60 degrees or less, about 45 degrees or less, or about 30 degrees or less relative to a circumference of perimeter of the header guide connector. The ears may slide upon walls (e.g., the walls may form a track) of the header guide connector but may restrict or prevent the header guide connector from being removed from the header recess. The header guide connector may include one or more ears upon a top so that the header guide connector is spaced within the guide recess, the ear contacts a rear side of a top surface of a guide recess, or both. The ears may retain the header guide connector within the header guide recess even when the header guide connector is rotated within the header recess. The ears may assist in creating tension between the header guide and the rail cap or support rail so that the seal is compressed by the panels, the hinges, the expansion caps, or a combination thereof. For example, the ears may connect the header guide to the header panel and when the header guide is in contact with a rail cap or a header panel the connection may pull the header panel down towards the rail cap or the header panel compressing a seal.

The one or more seals may function to prevent fluid, debris, or both from passing into an internal location under the tonneau cover. The one or more seals may be elastomeric. The one or more seals may be compressible. The one or more seals may be connected to or extend into a rail cap, a support rail, or both. The seal may be pressed into the rail cap, the support rail, or both to connect the seal thereto. The one or more seals may have one or more lines of contact. The one or more seals may have a cross-sectional shape that is “O”-shaped, “D”-shaped, oval, square, rectangular, diamond, shaped, or a combination thereof. The seal may be made of or include an elastomer. The seal may be made of an elastically deformable material that bounces back when the tonneau cover is in a stored position. The one or more seals may have more than one contact locations or lines of contact.

The seal fingers may extend outward from the seal. The seal fingers may extend above a plane of a top of a seal. The seal finger may be compressed with the seal when the panel contacts the seal. A channel may be formed between the seal, the seal finger, or both and a rail cap, a support rail, or both.

The channel may function to divert water from the tonneau cover, the rail cap, the support rail, or a combination to an external location so that the water is prevented from entering the tonneau cover. The channel may extend along an entire length of the tonneau cover. The channel may extend along a portion of a length of the tonneau cover. The channel may direct fluids into the stake pockets, out a tail gate, out a fluid channel through a rail cap, through a support rail, or a combination thereof. The channels may be located between a vertical wall of a rail cap, a vertical wall of a support rail, or both and a seal. The channel may be located entirely or partially under a panel, a hinge, an expansion cap, or a combination thereof. At least a portion of the channels may extend under a central panel.

The one or more central panels may cover a central portion of a bed. The one or more central panels may be located between a header panel and a tail panel. The one or more central panels may be a panel that is folded. The one or more central panels may be a first panel, second panel, third panel, fourth panel, or a fifth panel.

The one or more central panels may be connected by one or more hinges. The one or more central panels may be in communication with one or more tail panels.

The one or more tail panels function to end the tonneau cover, create a seal with a tailgate, or both. The one or more tail panels may extend over a tailgate, into communication with a tailgate, a rail cap of a tailgate, a support rail of a tailgate, or a combination thereof. The one or more tail panels may contact with the side walls and the tailgate. The one or more tail panels may lock a tonneau cover to a tailgate. The one or more tail panels may be a first panel rotated when the tonneau cover is moved from a closed position to a stored position. The tail panels may be the last panels moved when a tonneau cover is moved from a stored position to a closed position. The tail panels may include one or more tail extensions to extend the tail panel to a tailgate or over a tailgate.

The one or more tail extensions function to extend the tail panel over a tailgate. The one or more tail extensions may assist in locking a tonneau cover to a bed of a vehicle. The one or more tail extensions may mirror a shape of a tailgate. The one or more tail extensions may be straight, rounded, mirror the shape of the tailgate, be arcuate, or a combination thereof. The one or more tail extensions may form a terminal edge or may include one or more terminal edges.

The terminal edges of the tonneau cover may extend over a sidewall of a vehicle bed, a support rail, a rail cap, inside of the sidewalls of the vehicle bed, inside of the rail cap, inside of the support rail, or a combination thereof. The terminal edge may be located inside of the bed so that the tonneau cover may be flush or sub-flush. The panels, the hinges, the expansion caps or a combination thereof may all include one or more terminal edges.

The one or more hinges function to move or permit movement so that an interior of a bed of a vehicle is exposed or enclosed. The one or more hinges may function to permit one panel to move relative to another panel. The one or more hinges may rotate a panel about 90 degrees or more, about 135 degrees or more, about 180 degrees or more, about 181 degrees or more, or about 182 degrees or more relative to a second panel. The one or more hinges may rotate a panel about 270 degrees or less, about 225 degrees or less, about 190 degrees or less, or about 185 degrees or less relative to a second panel (e.g., about 181 to about 184 degrees). The hinges may support one end of a panel relative to a second panel. For example, when a first panel rotates over the second panel the hinge may support the first panel and maintain a gap between the first panel and the second panel. The hinges may form a cantilevered support. The hinges may connect a first panel to a second panel. The hinges may be a plurality of hinges. One hinge may connect each panel together. All of the hinges of the tonneau cover may be of a same style or type. Every hinge may be of a different style or type. The tonneau cover may include more than one style or type of hinge. The hinges may be an extended hinge, a hemispherical hinge, standing hinge, or a combination thereof. For example, if a tonneau cover has five panels the tonneau cover may have four different hinge types or styles. In another example, some of the hinges may include one or more header links, one or more panel links, or both.

The one or more header links, panel links, or both may function to connect to an end of a hinge to a panel and preferably a header panel, first panel, or both. The one or more header links, panel links, or both may connect a header panel to a first panel. The one or more header links, panel links, or both may extend from a first panel towards a second panel or vice versa. The one or more header links, panel links, or both may be directly connected to a panel. The one or more header links, panel links, or both may be connected to a frame that is connected to a panel. The one or more header links, panel links, or both may be part of a panel. The one or more header links, panel links, or both may be a monolithic part of a panel. For example, the header link, panel links, or both and panel may be formed at the same time of the same material. The one or more header links, panel links, or both may extend parallel to a top of the tonneau cover. A header link of a first panel may extend outward and contact a panel link of a second panel so that rotation of a first panel is prevented relative to a second panel, the first and second panel are stopped in a coplanar position, or both. The header links, panel links, or both may be sufficiently long so that when a header link of a first panel contacts a panel link of a second panel the first panel and the second panel are generally planar. Both panels may include panel links. A header link may be a panel link that is connected to a header panel. A header link may be connected to a header panel and a panel link may be connected to a panel and the header link and the panel link may be identical, mirror images of each other, or both. The header link, panel link, or both may include one or more frames.

The one or more frames may function to connect a header link, a panel link, or both to a respective panel. The one or more frames may function to connect a hinge and a panel together. The one or more frames may be located on an interior of a panel. The one or more frames may be located between two covers (e.g., a top cover and a bottom cover). The one or more frames may be connected to a core of a panel (e.g., a rigid piece that is located between the top cover and the bottom cover). The one or more frame may be a box, a rectangle, hollow, solid, have an open end, have a closed end, receive a portion of the core, have a smooth surface that faces the covers, have a recessed surface, have recesses that receive excess adhesive, or a combination thereof. The frame when connected to the covers, the core, or both may become rigid relative to the cover, the core, or both. The frame may rigidify the panel, a terminal edge or a panel, a location of a panel in contact with a hinge or that is part of a hinge, or a combination thereof. The frame may be rotationally static, longitudinally static, or both. One or more panels may be free of a frame. The panels may include a monolithic frame.

The frame may be connected to or include, a header link, a panel link, a hinge joint, a pocket, an expansion stop, a rotation stop, an expansion projection, a ball, a socket, a recess in a top surface, a recess in a bottom surface, or a combination thereof. One style of hinges may include a frame with a panel link or a header link extending from the frame and one or more rotation stops located at an end of the header link, the panel link, or both.

The one or more rotation stops function to maintain two panels in a generally planar relationship relative to each other. A first rotation stop functions to contact a second rotation stop to limit movement of a first panel relative to a second panel. The rotation stops may be located at ends of the header link, the panel link, or both. The rotation stops and panel links, header links, or both may form a generally “L” shape. The rotation stops may have a terminal end with a bulbous portion. The bulbous portion may assist in mating two rotation stops together. The rotation stops may be sufficiently rigid so that two panels are maintained in a planar relationship when the tonneau cover is in a closed position. A first rotation stop and a second rotation stop when in contact may restrict movement of two panels relative to each other in a first direction but may allow movement in a second direction. The rotation stops may be located between any panels listed herein (e.g., a header panel, tail panel, central panels, or a combination thereof). Preferably, the rotation stops are located between a header panel and first panel and extended hinges are located between other panels.

The one or more extended hinges function to connect two panels together. The one or more extended hinges function to support one or more panels above a plurality of intervening panels. The extended hinge may support a third panel above a first panel, second panel, fourth panel, or a combination thereof. The extended hinge may support one panel above three other panels. An extended hinge may connect a panel (e.g., third) to another panel (e.g., fourth) and create a space between the panels that is sufficiently large so that one or more and preferably two or more panels may fit between the panel and the another panel. The extended hinges may separate two panels by a distance. The distance may be equal to a thickness of one panel, a thickness of two panels, a thickness of three panels, a thickness that is slightly larger than one panel, slightly larger than two panels, slightly larger than three panels, slightly larger than four panels (e.g., 1 mm or more, 3 mm or more, 1 cm or less, 7 cm or less); or a combination thereof. The extended hinges may support one panel generally parallel to one or more other panels (e.g., within about ±5 degrees, about ±3 degrees or about ±1 degree). The extended hinges may support a first end of a panel generally parallel to one or more panels. The extended hinges may support a panel so that a gap is created between two generally parallel panels (e.g., 1 mm or more, 2 mm or more, 5 cm or less, 3 cm or less). The extended hinge may span a distance of 10 cm or more, about 15 cm or more, or even about 20 cm or more. The extended hinge may span a distance of about 50 cm or less, about 40 cm or less, about 30 cm or less, or about 25 cm or less. The extended hinge may include one or more spacer bars. The extended hinge may be free of spacer bars. The extended hinge may be a combination of spacer bars and hinge joints connected together. The extended hinge may be only hinge joints. Preferably, the extended hinge has between about 3 and 7 hinge joints (e.g., the hinge joints may be expansion links connected together) and one spacer bar.

The one or more hinge joints may function to permit one portion of a hinge to move relative to another portion of a hinge (e.g., an expansion link to rotate relative to another expansion link). The one or more hinge joints may be part of a hinge, an extended hinge, an expansion link, a hemispherical hinge, a standing hinge, or a combination thereof. The one or more hinge joints may be a location where two or more hinge components connect together or are movable relative to each other. The hinge joints may be a ball and socket.

The one or more hinge joints may a location where two expansion links are connected together and the expansion links move relative to each other. The one or more expansion links may move relative to each other so that a length of the hinge joint changes (e.g., expands or contracts). The one or more hinge joints may be between two expansion links, a spacer bar and an expansion link, an expansion link and a panel and/or frame, or a combination thereof. The one or more hinge joints may be part of a frame, a panel, a spacer bar, an expansion link, or a combination thereof when a connection between two parts of a hinge is created.

The one or more spacer bars may function to elongate or increase a distance that the extended joint covers or extends. The one or more spacer bars may be added in place of expansion links. The one or more spacer bars may support expansion links located on a first side, on a second side, or both sides of the one or more spacer bars. The one or more spacer bars may have a dimension (e.g., width (e.g., a dimension of the spacer bar that extends along a length of a bed)) that is substantially equal to a thickness of a number of panels, a thickness of panels stacked one over another (e.g., about one or more panels, about two or more panels, or about three or more panels). The one or more spacer bars may have a top surface that in the stored position is perpendicular to the panels. The one or more spacer bars may have a top surface that in the closed position is parallel to the surface of the panels or is coplanar with the panels.

The one or more spacer bars may support one panel over another panel. The one or more spacer bars may include one or more spacer recess (e.g., a socket), one or more fasteners (e.g., ball) or a combination thereof so that a panel is pivotable about a spacer bar, or vice versa. The one or more spacer bars may include one or more spacer bars may include one or more expansion projections, one or more pockets, or both. The one or more spacer bars may have a fixed length and may be movable as one panel is moved relative to another panel. The one or more spacer bars may have a first amount that is exposed in a first position and a second amount that is exposed in a second position. For example, a portion of a spacer bar may be covered by an expansion projection and as a hinge moves from a closed position to a stored position, more of the spacer bar may be exposed. The spacer bar may be a plurality of pieces connected together or one single piece. The spacer bar may be hollow, include a recess, or both. The spacer bar may include one or spacer caps that cover the hollow area, the recess, or both.

The one or more spacer caps function to extend a spacer bar over a seal, over a rail cap, over a support rail, beyond a panel, over a side wall of a vehicle, or a combination thereof. The one or more spacer caps may function to prevent fluid from passing through a hinge, proximate to a spacer bar, between a spacer bar and a seal, or a combination thereof. The one or more spacer caps may close one or both sides of a spacer bar. The one or more spacer caps may close one or more sides of a spacer bar. The one or more spacer caps may be angled so that the tonneau cover may be located flush or sub-flush within the bed, relative to the rail caps, relative to the support rail, relative to the side walls of the vehicle, relative to a tailgate of a vehicle, or a combination thereof. The one or more spacer caps may contact a seal, create a seal, or both to prevent fluid from penetrating the tonneau cover, entering into the bed, or both. The one or more spacer caps may guide fluid into a channel, trough, stake pocket, or a combination thereof. The spacer cap may have a terminal end that extends to be co-planar with a terminal end of a panel. The spacer caps may be substantially identical to an expansion cap except the spacer cap may be larger than the expansion caps. The teachings of the expansion caps are expressly incorporated herein with regard to the elements of the expansion cap such as the tab, connection feature, cap, extension taper, vertical wall, or a combination thereof, all of which the spacer cap may include such that the teachings herein as to those features may apply to the spacer cap. The spacer caps may extend cantilever from a spacer bar. The spacer caps, the spacer bars, or both may include one or more fasteners, one or more spacer recesses, or both.

The one or more spacer recesses may function to receive one or more fasteners to form a connection. The one or more spacer recesses may include an open space that one or more fasteners extend into to create a connection. The one or more spacer recesses may be a closed shape (e.g., circle, oval, square). The one or more spacer recesses may be an open shape (e.g., a “u”, a “c”). The one or more spacer recesses may receive a threaded member, a connection feature, an elastomeric member, an expandable member, a pin, a set screw, a nut and bolt, or a combination thereof. The one or more spacer recesses may form a snap fit. The one or more spacer recesses may create a friction fit with a fastener. The one or more spacer recesses may connect to and receive a fastener, a bumper, or both.

The spacer recesses may be located within expansion links, spacer bars, or both.

The one or more expansion links may function to connect to another expansion links or expansion links of a frame. The one or more expansion links may function to connect together and supportively move relative to one another. One expansion link may have a portion (e.g., an expansion projection) that extends into (e.g., a pocket) another expansion link and the expansion links may move relative to each other. The expansion links may move a pre-determined distance relative to each other. The expansion links may rotate relative to each other, longitudinally move, or both so that a panel is moved out of a plane into a second plane above another panel. The one or more expansion links may each rotate about 20 degrees or more, about 25 degrees or more, about 30 degrees or more (e.g., each expansion link may move a panel a rotational distance of about 32 degrees). The expansion links may each rotate about 60 degrees or less, about 50 degrees or less, about 45 degrees or less, about 40 degrees or less, or about 35 degrees or less. The expansion links as a hinge may rotate to an angle of about 175 degrees or more, about 179 degrees or more, about 180 degrees or more, about 181 degrees or more, or about 182 degrees or more. The expansion links as a hinge may rotate to an angle of about 190 degrees or less or about 185 degrees or less. The number of expansion links may be determined by dividing a desired angle of rotation by the rotation distance of each expansion link. For example, if an angle of 186 degrees is desired and 6 expansion links are used then each expansion link may rotate an angle of about 31 degrees. The expansion links as a hinge may rotate to an angle above 180 degrees so that an opposing end of a panel is angled towards another panel and contacts a support on a surface of the panel so that the opposing end is supported. An angle each expansion link rotates may be changed by adjusting a length of the expansion stop, the expansion projection or both. For example, if an expansion stop and expansion projection are both 2 mm in length then the expansion link may rotate 32 degrees and if the expansion projection length is shortened to 1.8 mm the expansion link may rotate 28 degrees. The expansion links may be connected together by an expansion projection of one expansion link extending into a pocket of another expansion link. The expansion projection of one expansion link may be prevented from being removed or falling out of a pocket of another expansion link by a cover connecting the two expansion links together and preventing movement of one expansion link relative to the other expansion link so that they become disconnected.

The one or more expansion projections may function to connect a frame or an expansion link to another frame or expansion link. The one or more expansion projections may function to extend into a pocket. The one or more expansion projections may move within a pocket.

The one or more expansion projections may have a “V” shape, a “U” shape, or both. The one or more expansion projections may fit entirely within a pocket of an adjacent frame or expansion link. The one or more expansion projections may move within a pocket as one panel is moved relative to another panel. The expansion projections may fit entirely within the pocket when the tonneau cover is in the closed position. The expansion projections may partially extend out of the pocket when the tonneau cover is moved into or in the stored position. The expansion projection may extend outward in a first direction and then curve backward in a second direction. The expansion projection may have a flat portion, a linear portion, or both. The expansion projection may have a curved portion, and arcuate portion, or both. The curved portion may curve under the linear portion. A length of the expansion projection may be varied to change a distance each hinge joint travels. A length of the expansion projection, a length of an expansion stop, or both may be lengthened or shortened to vary an amount of rotation of each hinge joint or each expansion link. The curved portion may mirror a shape of the pocket. The curved portion may have a complementary fit to the pocket. The curved portion may have a length of about 1 mm or more, about 2 mm or more, about 3 mm or more, about 5 mm or more, about 1 cm or more, about 2 cm or more, or about 4 cm or more. The curved portion may have a length of about 10 cm or less, about 7 cm or less, or about 5 cm or less. The expansion projection may have a terminal end (e.g., projection stop) that restricts movement of the expansion projection within the pocket.

The one or more projection stops may move within a pocket. The one or more projection stops may restrict movement in a first direction or a second direction. The one or more projection stops may contact one or more expansion stops to restrict movement in the closed position, the stored position, or both. The one or more projection stops may assist in maintaining a hinge in a stored position. A length of an expansion projection, a length of a pocket (e.g., a distance the projection stop can move relative to an expansion stop) may determine an angle that a hinge may move or an angle that an expansion link may move. The expansion stop may be located at an end of an arcuate portion of the expansion projection. The expansion stop may be located under a planar portion of the expansion projection. The expansion stop may be located under a hinge step or in a same plane as a hinge step. The hinge step may separate an expansion projection and a pocket.

The hinge step may function to receive a portion of an adjacent expansion link when the expansion links are moved to a stored position. The hinge step may function to be free of contact with a cover (e.g., a disconnection location). The hinge step may assist one expansion link in rotating relative to another expansion link. The hinge step may create a pivot point. The hinge step may be a reduction in wall thickness of the upper surface (e.g., first wall) of an expansion link. The hinge step may be located on a terminal end of the first wall, the upper surface, or both. The hinge step may be a reduction in thickness of the upper surface so that the cover may disconnect and the expansion links may rotate relative to each other into a stored position.

The one or more upper surfaces may function to support objects on the tonneau cover, to close a bed, prevent fluid and debris from entering a bed, or a combination thereof. The one or more upper surfaces may be a top surface of an expansion cap. The upper surface may be an upper most layer of the expansion cap, spacer bar, panels, or a combination thereof. The panels, hinges, spacer bars, spacer caps, expansion caps, or a combination thereof may each include an upper surface. The upper surface of each component may be coplanar when the tonneau cover is in the closed position. The upper surface of each component may be located within one or more planes, the upper surfaces may face one another, the upper surfaces may be parallel, or a combination thereof when the one or more components of the tonneau cover are moved into the stored position. The one or more upper surfaces may have a cover that extends thereover. The one or more upper surfaces may extend over one or more pockets.

The pocket may function to receive all or a portion of an expansion projection. The pocket may guide an expansion projection when the expansion projection moves within the pocket. The pocket may support the expansion projection so that as the panels move between a stored position and a closed position, the panels may maintain a spaced apart relationship. The pocket may allow for a limited range of rotational movement. The pocket may allow an expansion projection to move from a first end of a pocket to a second end of the pocket. The pocket may have stops at one or both ends that stop the expansion link at predetermined locations so that each link moves a predetermined distance. In one direction, a projection stop may contact an expansion stop to determine a length of movement of a length of rotation. In a second direction, a top surface or a planar portion of a pocket may contact a hinge step to prevent further rotation of the expansion links relative to each other. A shape of the pocket and a shape of the expansion projection may be mirror images, complementary, or both. The expansion projection may have a shape similar to that of the pocket and may fit within the pocket. The pocket may have an opening that allows the expansion projection to move between a stored position and a closed position. The opening may be sufficiently small that the expansion projection may not be pulled through the opening. The expansion projection may move laterally along the pocket for installation but may not longitudinally or rotationally move out of the pocket. The pocket may be or include a generally “V” shaped portion, a generally “U” shaped portion, or both. The pocket may be formed of one or more walls, two or more walls, or both. The pocket may have a one or more linear walls, one or more arcuate walls, one or more stop walls, or a combination thereof. The pocket may include two or more walls that form an interior space.

The second wall may be generally arcuate. The second wall may extend beyond the first wall. The second wall may extend in two directions from the first wall. For example, when viewed in a cross-sectional view the second wall may move down and to the right. The second wall may extend at a first slope and then towards an end of the second wall the slope may lessen. The slope of the second wall may reduce to zero at some point along the second wall. A length of a second wall may determine an amount of rotation of each expansion link of a hinge. The slope of the second wall may be negative at a location along the second wall. The second wall may have an arc that terminates at a third wall.

The third wall may function to fully or partially close the pocket. The third wall may function as a stop. The third wall may be an expansion stop. The expansion stop may close a portion of the pocket. The expansion stop may restrict movement of the expansion projection. The expansion projection may move along the second wall until the projection stop contacts the expansion stop. The expansion stop may contact the projection stop to support an expansion link, a panel, or both in a stored position. A distance of the expansion stop from the first wall or a length of a second wall may determine an angle that an expansion projection may move within the pocket. The expansion stop and the projection stop may contact each other to support a hinge in a stored position, limit movement of an expansion link, or both. The expansion stop may be angled backwards towards the second wall, the first wall, or both. The expansion stop may extend at an acute angle relative to the second wall. The expansion stop may extend at an angle of about 15 degrees or more, about 25 degrees or more, or about 35 degrees or more relative to the second wall.

A body of the track arm may be located behind the narrow neck region. The body of the track arm may stabilize the slider within the track. A track connector may extend outward from the body towards the lower track wall, the upper track wall, or both.

The track connector may function to connect the slider to a track, prevent a slider from moving when the slider is connected to tether or an anchor, or both. The track connector may contact a wall of the track to prevent movement of the slider. The track connector preferably contacts the lower track wall. The track connector may be complementary in shape to the lower track wall. The track connector may contact a stop a detent or both. The track connector may prevent rotation of the slider relative to the track. The track connector may prevent the slider from being pulled vertically within the track. The track connector may have a generally triangular cross-section. The track connector may extend from the body and outward relative to the connection arm. The track connector may be located under the connection arm, the track recess, or both. The track connector and the track recess may be located opposite each other and may form a narrow neck region.

The narrow neck region may be a region of the slider that extend out of the track, between the upper track wall and the lower track wall, or both. The narrow neck region may function to permit the connection arm to extend out of a track while retaining the slider within the track. The narrow neck region may form one or more shoulders behind the narrow neck that contact the upper track wall, the lower track wall, or both so that the slider is retained within the track. The narrow neck region may be formed by the track connector and the track recess. A shoulder may be formed at or behind the track connector, the track recess, or both that permits removal of the slider form the track. The track connector, the track recess, or both may be an absence of material. Preferably, the track connector, the track recess, or both include a depression and a shoulder. The depression receives the upper track wall, the lower track wall or both and the shoulder contacts an interior of the upper track wall, the lower track wall, or both. The track connector and the track recess may be located on opposing sides of a connection arm.

The one or more track recesses may function to receive a portion of an upper track wall, restrict the slider from being removed from the track, or both. The track recess may have a complementary fit within the track, with the upper track wall, or both. The track recess may directly oppose the track connector. The connection arm may extend between the track recess and the track connector. The track recess may be an absence of material. The track recess may be located on an edge of the body, in the body, between the body and the connection arm, or a combination thereof. The track recess may receive a portion of the tether, assist in connecting the tether to the connection recess, or both.

The tether may function to connect a tonneau cover to a bed, a vehicle, an anchor, or a combination thereof. The tether may restrict movement in a longitudinal direction, a lateral direction, transverse to the bed, longitudinal to the bed, or a combination thereof. The tether may be rigid. The tether may be plastically deformable. The tether may be elastically deformably. Preferably, the tether is pliable but free of stretch.

The track wall may function retain the slider within the tonneau cover and assist in connecting the tonneau cover to the bed, a vehicle, an anchor, or a combination thereof. The track wall may permit the slider to move laterally or in a transverse direction. The track wall may prevent longitudinal movement of the slider. The track wall may prevent the slider from being removed from the tonneau cover, the track, the header panel, or a combination thereof. The track wall may include an upper track wall and a lower track wall. The upper track wall and the lower track wall may be connected at ends. The upper track wall and the lower track wall may be free of any connection (e.g., direct connection). The upper track wall and the lower track wall may be separated by one or more tracks. The upper track wall and the lower track wall may be directly connected to each other at a central location of the header panel (e.g., in a middle). The upper track wall and the lower track wall may be indirectly connected. The upper track wall and the lower track wall may each contact a portion of a slider. Only the upper track wall or only the lower track wall may contact the slider. The lower track wall may contact a track connector. The lower track wall, upper track wall, or both may have one or more stops, two or more stops, four or more stops, or six or more stops that a slider contacts to restrict lateral movement of the slider once the slider is moved into a locking position. The lower track wall, the upper track wall, or both may be free of any stops. The lower track wall, the upper track wall, or both may be substantially smooth. The lower track wall, the upper track wall, or both may approach each other and be located on opposite sides of a narrow neck region, extend into a track recess, track connector, or both. The upper track wall may prevent the slider from tipping or rotating within the track. The lower track wall may prevent longitudinal movement of the slider relative to the track, the header panel, or both. The lower track wall may terminate at a lip.

The lip may function to restrict lateral movement of the slider. The lip may lock the slider in place when a force is applied to the slider by the tether. The lip and track connector may have complementary shapes. The lip may be generally triangular in shape. The lip may extend beyond a remainder of a header panel. The lip may be located closest to a vehicle, a cab, an end of a bed, or a combination thereof. The lip may receive the track connector and prevent rotation of the track connector and the slider when the tonneau cover and bed, vehicle, anchor, or a combination thereof are connected. The tonneau connector including the lip, track, slider, and tether, may lock a header panel to a bed and one or more rotary locks may assist in connecting other panels (e.g., central panels) to a bed.

The one or more panel extensions may be made of or include metal, plastic, a polymer, nylon, a thermoplastic, or a combination thereof. The one or more panel extensions may extend from a panel towards a hinge, under a hinge, or both. The one or more panel extensions may extend into or under a rail lock to lock a panel in place. The one or more panel extensions may rotate under the rail lock as a panel is closed. The one or more panel extensions may prevent a panel from being vertically lifted when then then panels are in a closed position. The one or more panel extensions may be located inside of an outer edge of a panel. The one or more panel extension may begin to lock or unlock a panel when the panel is partially open (e.g., an angle of about 25 degrees or more, about 35 degrees or more, about 45 degrees or more, or about 60 degrees or less). The one or more panel extensions may extend from open, to partially opened, and then locked as the panel moves from a stored position to closed position. When the panel is partially opening the panel may continue to be locked. The panel may be locked as long as a portion of the panel extension extends under a portion of a rail lock.

The one or more rail locks may function to contact a panel extension and prevent a panel from being opened when the rail lock and the panel extension are connected. The one or more rail locks may extend above a rail cap, above a support rail, or both so that a space is formed between the rail lock and the rail cap, the support rail, or both. The one or more rail locks may extend in a direction opposite to the panel extensions. The one or more rail locks and the one or more panel extensions may extend towards each other. The one or more rail locks may be spaced apart from the rail cap, the support rail or both and the panel extension may extend into the space so that the panel extension prevents lifting of a panel. The rail locks may have a width that is substantially equal to the panel extension. The tonneau cover may have an equal number of rail locks as panel extensions. The rail locks may extend in a single plane. Preferably, the rail locks begin at a rail attachment, rail cap, support rail or a combination thereof and extend upward away from the rail cap, rail attachment, rail support, or a combination thereof and the plateau in a second plane. The first plane and the second plane may be parallel to each other. The first plane may partially extend over the second plane. Preferably, the first plane and the second plane do not overlap.
